Lesson 1 & 2: Using a Number Line to Model Addition & Opposite Quantities Combine to Make Zero Skills/ I can: 1. Show that an integer and it’s opposite will always have the sum of zero, using a number line. 2. Demonstrate addition of integers using arrows on a number line. 3. Describe real-world situations where opposite quantities combine to make zero.

Integer Game 1.A student serves as the dealer (as well as a player) and provides each player with 4 cards. 2.The dealer turns one more card face up on the playing surface, starting a discard pile. The remaining cards become a draw pile. 3.The player to the dealer’s right begins play. On his or her turn, a player may select the top card from either the discard pile or the draw pile. They then discard one of their cards on discard pile. Players goal: a. Have your hand’s total card value stay as close to zero as possible. b. Each turn determines how the card drawn affects your total card value. c.Decide which card to discard, to keep the total value of their hand as close to zero as possible. 4.Play continues with the next player, in the same manner, until all players have picked up and discarded a card four times. 5.The player(s) with a score of zero (or closest to zero) wins the round.

With your team, play the integer. Remember each person picks up a card and discards a card four times. The person with the hand closest to zero wins that round! Play as many rounds as you can in the next ______ minutes.

Reflection Questions (Output – Left Side) 1.What is the result of two cards that are opposite of each other? Example: 5 and -5 or -12 and 12 2.Give two examples of how positive and negative quantities are used in the real-world. 3.Give two examples of the meaning of zero in the real-world. 4.How are opposite quantities used in the real-world?

Lesson 1: Opposite Quantities Combine to Make Zero Objectives Students add positive integers by counting up and negative integers by counting down Students know the opposite of a number is called the additive inverse because the sum of the two numbers is zero.

Lesson 2: Using the Number Line to Model Addition of Integers Objective: 1.Model integer addition on the number line using horizontal arrows. 2.Recognize that the length of the arrow on the number line is the absolute value of the integer. 3.Add arrows. Given several arrows, indicate the number that the arrows represent (the sum).

Suppose you received $10 from your favorite aunt on your birthday. You spent $4 on snacks. Using addition, how would you write a number sentence that represents this situation?
